This invention relates :to bolt work for safes,rand"morewparticularlyrelates to bolt orkssuitable for association with thedoors.ofsfireproofisaltes, cabinets-and similar strum 5 tures.

*Heretoiore it has :been customary 'to build :the bolt work into :thedoor, and this has required :much :detail assembly work, includiing'thefitting 0f :the separate; parts of the bolt'work to the :door. Usually:the bolt 'WOIki has been built llHtO the door intermediate-the frontand rear Walls thereof.

O'ne of 'the principal objects offthisinwenti'on is itoielimina te thenecessity of build- .ing theibolt Work-into the-door and to avoid thetimennd labor irequired :to assemble the parts of .the sbolt work.separately-on the door. A further object of this invention :is toprovide bolt WOIk :construction which permits the door itself ito dorm.a sealed enclosure::in which the filling :may be placed. :Anoth er:object of this invention 'is to provide Ibolt ork-fora saiesdoor' whichrender-s it possible foriithe'zdoor to 'be so'constructed that thefilling is contained in a sealed chamber ftherein. A further object ofthis invention is to provide bolt wvork for safe'doors which is shieldedfrom being damaged by dusting of the door filling; or

3o-other cleteriorating'influences. A further object-of thisinv-ention:is :to provide "bolt Work 0f simple and durable construction, and boltWork -which'may'be applied ItO 5a safe doorreadily and easily.(Dtherobjects of-this'invention Will be ingpartobvious and "in=partpointed out hereinafter.

In "accordance With this inyentiom the bolt Work construction is-'assembled as .a separate and complete unit apart from the 40 doorand isthereafterattached to the rear of the door by simple -means andconnected wi th the combination operating spindle and th' e handle foroperating the bolt -work.

In-order that amlearer understanding of this invention may be had,attention .isrhe'ree 'by directed to the accompanying drawings tfo'rminga part!of this.applicationranchillustrating certain poss'ibleembodiments of the invention. In "the drawings, Fig. '1 is :a

A cam plate 26 is secured to the pin 20, as

by means of nut 27, and has a pin 28 which seats between two shouldersor projections 29 and 30 formed on the plate 22. One end of plate 22 isflanged, as at 31, and is positioned near the locking edge of'the door.A bolt 32 is secured to this flange 31 of plate 22, so that by slidingthe plate 22 the bolt 32 may be locked andunlocked 1 Cam plate 26 hasanother pin 33 which is connected by a link 34 to a bolt 35 which isdisposed at the top of the housing for movement into and out of lockingposition. In a similar manner other pins 36 and 37 on the cam plate 26are connected by means of links 38 and 39 to bolts 40 and 41, positionedrespectively at the hinge edge and bottom edge otthe housing formovement with the cam plate 26 into and out of locking position. Thecombinationlock mechanism inthe housing 19 has associated with it theconventional locking dog 42, which abuts the sliding plate 22 and thusdomihates not only the movement of this plate and the bolt 32 but alsomovement of the cam plate 26 and the movement of the bolts 35,401and 41.i

It will beapparent from the above that the bolt. work is thus assembledinto a separate and complete unit which may be applied to the rear ofthe safe door conveniently and easily. For instance, this housingcontaining the bolt work may be secured to the rear wall 6 of the doorby means of bolts 43. To permit access to the interior of the housingfor this purpose, the rear plate 16 of the housing may be removedwithout disturbing the assembly of the bolt work. This rear plate ma besecured to the housing b means of suitable'screws 44.

If the door is of the type shown in Fig. 6, wherein a separate valvedoor is secured to the rear of the main door 46 by means of bolts 47,these same bolts may be utilized to secure the bolt work unit to thedoor at the rear of the valve door 45. In this modification of the safea side wall of the safe is shown at. 48. The door hasa front plate 49and a rear plate 50 and contains sealed-in insulation 51.

The jamb walls of the safes to which the bolt work unit is applied areprovided with suitable shoulders behind which the bolts engage. Forinstance, in the structure shown in'Fig. 1 thesafe is provided with abolt recess 52, and in the modification shown in Fig. 6 the recess forthe bolt is shown at 53. i

The pin 20 of the bolt work is provided with a key or tooth 54 which isadapted to interlock in a corres onding recess 55 formed in the end ofte spindle 13 to establish a connection between the operating handle 14and the bolt work, so that the bolt workis operable in the usual mannerfrom the-exterior of the safe door This connection requires no separateapplication of parts nor ad ustments.

This invention permits the door to be built up without any bolt work,and in the form of a sealed compartment whichpro- .tects the cast-infilling from atmospherical changes. The separate and completelyassembled bolt work unit may be securely attached to the rear of thisdoor readily and easily. When attached to the door, the combination lockand the bolt work are operable in the usual manner from the outside ofthe door. When it is desired to unlock the safe, the combination lock isfirst manipulated to place thelocking dog 42 out of engagement with theplate 22. Then by merely turning the handle 14 the cam plate 26 isrotated, and by reason of the connections between this plate and thebolts 32, 35, 40 and 41, these bolts are simultaneously retracted andthe safe unlocked. The safe is locked by rotating the handle 14 in thereverse direction, and, if desired, the combination lock is operated tocause the plate 22 to be dogged by the locking dog 42, so that the safecannot be again unlocked until the combination lock has been properlyadjusted.

In mounting the bolt work, the plate 15 may be secured to the doorbefore the bolt work is mounted on this plate; instead of the bolt workbeing re-assembled thereon.

It will be noted tiat the bolt work is confined in a compartment whichis entirely separatefrom thecompartment in the door in which is thefilling material. Thus the bolt work is protected from damage whichmight be caused by dusting of the door filling, or other deterioratinginfluences.

As many changes could be made in the above construction and as manyapparently widely difierent embodiments of this invention could be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description.

or shown in the accompanyin drawings shall be interpreted asillustrativeand not in a limiting sense.
